Explain how to use grouping symbols to organize information appropriately.

Grouping symbols in mathematics are the symbols which are used to group numbers or variables.There are three common types of grouping symbols such as parentheses ( ), brackets [ ], and braces { }.

There are some rules such as PEDMAS [parentheses,exponents,divide,multiply,addition,subtraction]or BEDMAS [brackets,exponents,divide,multiply,addition,subtraction] and BODMAS [bracket,of,divide,multiply,addition,subtraction] which are used in sequence from left to right to organize information appropriately and simplify the problem to get the answer.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
